## What is Train Libre?

Train Libre is a private, open-source workout and nutrition tracker for people who want serious logging without giving up control of their data. It is offline-first: no account, no social feeds, no gamification, no ads, and no commercial tracking or data selling.

Track your workouts, calories, bodyweight, and muscle recovery in one focused app, with secure local storage and optional Apple Health integration.

WHY TRAIN LIBRE IS DIFFERENT:
• Offline-First: No account and no network connection required. Your training and nutrition data stays in your device's sandbox.
• Privacy by Design: No ads, no ad trackers, no session recording, no user profiles. Usage statistics are optional and off by default — they never contain health data or your IP address, and you can turn them off and request erasure at any time.
• Structured Gym Tracking: Built for progressive overload and rigorous logging, not addictive engagement hooks.
• Transparent Analytics: Understand your long-term physical trends through clear, math-based insights.

KEY FEATURES:

1. ADVANCED WORKOUT LOGGING
• Log workouts set by set, including warm-ups, working sets, failure sets, and dropsets.
• Track precise metrics: reps, weight, and RPE / RIR (Rate of Perceived Exertion / Reps in Reserve).
• Build reusable routines, add custom exercises, and review your full session history.

2. SCIENCE-BASED NUTRITION & TDEE
• Log meals, calories, macronutrients, hydration, caffeine, creatine, and custom supplements.
• Adaptive Energy Expenditure Engine: a Kalman filter-based Bayesian TDEE estimator calculates your true maintenance calories dynamically from your actual scale weight and nutrition data.

3. PHYSICAL RECOVERY TRACKING
• Visual Recovery Heatmap: monitor muscle readiness based on localized volume, training effort, and recent load.
• Comprehensive stats for PRs, total training volume, consistency, body measurements, and physical vitals.

4. NATIVE HEALTH SYNC
• Optional integration to read physical metrics (steps, sleep, pulse) and feed them into your local recovery tracking.
• Completely local, secure, and user-controlled.

5. BYOK AI MEAL CAPTURE (Optional)
• Bring Your Own Key (BYOK): optional AI meal recognition that runs on your own API key. Disabled by default.
• State-Aware Matching: a local "Top-N Fuzzy Alternatives" system integrated with Open Food Facts matches your plate accurately while strictly preventing hallucinations.
• 100% Transparent: every AI suggestion is fully reviewable and adjustable before saving.

DISCLAIMER:
Train Libre is not a medical application. Algorithmic recovery feedback, sleep tracking, and physical vital metrics are intended strictly for personal athletic tracking and training guidance. They do not constitute, and must not replace, professional medical diagnosis or treatment.

OPEN SOURCE & OPEN DATA:
Built transparently on trusted community catalogs from Open Food Facts and the wger exercise database. The full source code is publicly accessible, so our privacy claims can be verified rather than just believed.


## Version history (last 4 releases)

### 1.1.1 — 2026-08-13

Minor bug fixes

### 1.1.0 — 2026-08-12

Live Activity & Dynamic Island: Follow your running workout straight from the Lock Screen and the Dynamic Island - current exercise, set, weight and rest countdown, without unlocking your phone. Skip or extend the rest timer right there.

Home & Lock Screen Widgets: New widgets for your last workout, muscle recovery, 7-day steps, body measurements and today's nutrition. Add them to the Home Screen or the Lock Screen and see your numbers at a glance.

Siri, Shortcuts & Action Button: Barcode scanner, AI meal capture, start workout, add water, log a supplement, add a measurement and add food are now available as Shortcuts, Control Center buttons and Action Button mappings.

Faster catalog updates: The database update screen no longer stalls near the end - the slow step behind it now takes milliseconds instead of about 20 seconds.

Straight to your next set: Opening a running workout now scrolls directly to the exercise with the next open set.

### 1.0.0 — 2026-08-11

iCloud Backup & Restore: Your data now backs up automatically to iCloud and restores in one tap when you get a new device or reinstall the app.

Visual refresh: A cleaner look throughout, with refined glass effects, smoother dark/light mode surfaces, and fixed contrast issues that made some text and buttons hard to see.

Big performance boost: Smoother scrolling and faster navigation across Diary, Statistics, and Workout screens, especially on newer high-refresh-rate displays.

Full Imperial unit support: Pounds, inches, and miles now work correctly everywhere in the app, not just in some screens.

Cardio tracking: New personal records for distance, duration, and pace, kept separate from your strength stats so your analytics stay accurate.

More reliable data saving: Fixed bugs where edited workout history, rest timers, and personal records could fail to save.

Faster, more reliable imports: CSV workout imports are now dramatically faster and skip duplicates automatically.

Security improvements: Hardened backup import/export to better protect your data.

Optional usage statistics: You can now help improve Train Libre by sharing usage statistics. Off by default, contains no health data, and can be turned off and erased at any time in Settings.
